Multifunctional quick-acting fuel oil additive

Abstract

The invention provides a multifunctional quick-acting fuel oil additive which comprises the following components (by weight): 30-40% of multicomponent diluents, 10-20% of catalysts, 5-10% of organic ether, 3-5% of cyclopentadienyl tricarbonyl manganese, 5-15% of smoke-removing anti-knock agents, and 5-20% of ethoxyethyl acetate. The above components are added into an enclosed stirrer in order, stirred for 10-15 min, and sieved by a metal mesh to obtain the finished product. The beneficial effects of the invention are that the fuel oil additive can not only increase the fuel oil octane number and combustion performance, but also improve fuel oil storage and usage stability, prevent fuel oil from oxidation and gum formation, comprehensively remove fuel oil soluble gum, insoluble precipitated gum, adhesive gum and carburettor coked charcoal, reduce tail gas discharge harmful indexes, and form unique synergistic effect. The fuel oil additive has extensive applications, has flexibility, is suitable for gasoline and diesel oil with different models, and can be randomly blended into commercial unleaded gasoline such as 90#, 93#, 95# and the like, and -10# diesel oil according to its properties.

Description

technical field [0001] The invention belongs to the field of petrochemical industry, in particular to a multifunctional fast-acting fuel additive. Background technique [0002] At present, gasoline fractions obtained from crude oil atmospheric and vacuum distillation, thermal cracking, catalysis, cracking, alkylation and other refining units do not meet the standards of the gasoline performance category of the nationally specified brand, and different additives need to be added according to the performance of the product gasoline. After blending, it can reach the standard of commercial gasoline required by the market. [0003] Among the additives for blending gasoline products in the past, the octane regulators were all satisfied with "ethyl liquid" with tetraethyl lead as the main component. However, because this additive contains highly toxic substances, it seriously endangers the ecological environment, so The production and application have been stopped successively at ...

Problems solved by technology

[0003] Among the additives for blending gasoline products in the past, the octane regulators were all satisfied with "ethyl liquid" with tetraethyl lead as the main component. However, because this additive contains highly toxic substances, it seriously endangers the ecological environment, so Production and application have been stopped at home and abroad. Later, petrochemical enterprises produced methyl tert-butyl ether (MTBE) to replace "ethyl liquid". However, due to large investment in equipment and processes, and internal digestion, it cannot be widely used.
